SPECIFICATION forming part of Letters Patent No. 85,973, dated October 2, 1883. Application filed June 15, lSi-fl. (No model.)

To all whom, it may concern/.-

Iie it known that 1, SA in U ET. LIT. (owl-IRAN, oi IIGverett, in the county of Middlesex and, State ofllljassachusetts, a citizen oi. the. United States, have invented a new and useful ]Improvemcnt in Ghurns and Like Apparatus for Use in the Manuiacture of Artificial ll'iutter, 850., of which the following is a specification.

My improvement relates, particularly, to churns and the like apparatus for use in the manufacture of artificial butter and like purposes; and it consists in providing the churn with means whereby the temperature of its contents may be regulated, as below described.

Uhurns and like apparatus have heretofore been iacketedthat is, set into a chamber capable of containing a fluid which can impart its temperature, in a greater or less degree, to the substance in the churn; but no such churns, so far as I now know, are provi ded with means for regulating this temperature-that is, means of filling this chamber with either a hot orcold fluid from a constant source of supply, or for combining in the chamber two fluids of different temperatures in such a proportion that a required tempera ture may be had, or for keeping up a constant circulation of the temperature-controlling medium about the churn, 'so that the temperature, once attained, .may be kept constantly at the same degree.

In the drawings is shown the best form of churn now known to me embodying my in,- vention, Figure 1 being a vertical section, and Fig. 2 a top view, of the churn alone.

A is the churn, provided with two sets of floats, one attached directly to the shaft B and the other to the sleeve 13, the shaft and the sleeve being adapted to be rotated in 0pposite directions by the gearing O, as shown. The churn is surrounded by ajacket, D, closed at the top, and provided with one inlet-pipe, E, and two outlet-pipes, F and G. Theinletpipe E has connected with it two pipes, E and E each provided with a stop-cock of some kind, one of these pipes being for the purpose of supplying steam or hot water, and the other for the purpose of supplying cold water through the inlet-pipe E to the chamber around the churn. In this way I avoid an extra opening into the chamber around the churn, which I should have if both pipes E and E connected attained, be kept by reason of the with thcjacket. The outlet-pipe F is provided with. a stop-cock, and is for the purpose of drawing off from the chamber the water of coinlensation or the cold water which has been supplied from the pipe 1 The outlet-pipe G is an overflow, and, if desired, serves, with the inlet-pipe .E, to keep up a constant circulation of steam or cold water about the churn.

H and I are pipes for the purpose of filling the churn and emptying it, respectively.

The operation of my improvement is as fol lows: It being desired to heat the contents of the churn, the stopcock connected with the pipe E is opened, and a continuous supply of steam sufficient for the purpose is allowed to enter the jacket through inlet-pipe E. As this pipe E enters the jacket near the bottom, the steam will circulate around the churn, within the jacket, until finally it either con- (lenses or escapes through the overflow G. If it is desired, then, to cool the mass, the stopcock in pipe E being closed, the stop-cock in pipe .E is opened and the cold water fills the chamber and flows out through the overflow G, keeping up a constant circulation, and cooling the mass in the churn. very quickly. If, then, it is desired to heat the mass again, or allow it to acquire the temperature of the room in which the churn stands, the water can be drawn off through the outlet F, and the steam be turned on again. or not, as desired. In this way the temperature of the mass can be regulated at pleasure. Moreover, hot and cold water may be mixed together and fed into the chamber, and so any required degree of temperature be attained in the mass, and, once means for keeping up a constant circulation, above re ferred to.

.T t is obvious that my improvement may be embodied in a variety of ways other than the above-as, for example, by suitable coils of pipes passing around the churn, either inside or outside; but the churn shown in the drawings is simpler than any other. Moreover, in it floats can be used larger and better adapted for thoroughly agitating the massthan where the churn is provided. with coils of pipe in its interior.

The churn and its jacket shouldbe made of metal, depending in thickness upon the pressure of steam or water to be used; If thought best, hot and cold air can be used in this churn instead of steam, or hot and cold water.

as above described, whereby heated or chilled 15 fluid may be fed into said chamber, circulated throng-hit, and then pass out of it, all substantially as set forth. I 3. The churn A, provided with the jacket B, inlet-pipes E E E, and outlet-pipes F and 20 G, as described.
